Surrey begins $718K sewer inspection in North Surrey to cut rainwater inflow, protect environment, and reduce costly strain on Metro Vancouver’s system.
Surrey launches major sewer inspection to curb overflow
Contract awarded to tackle rising sewer challenges
The City of Surrey has approved a $652,881 contract with Dougness Holdings Ltd. to inspect and test North Surrey’s sewer system over the next three years. Council gave its approval on September 29, setting a maximum spending limit of $718,200 after reviewing five competing bids.
Why the city is acting now
City officials say excess rainwater entering the sanitary sewer network has become a “significant” problem. During heavy rains, water inflow and infiltration can triple normal flows, surpassing Metro Vancouver’s allowance of 11,200 litres per hectare per day.
Environmental and financial impact
Scott Neuman, Surrey’s general manager of engineering, warned council that the added flow increases treatment and conveyance costs, reduces system capacity for growth, and places stress on the environment. Addressing leaks is critical to maintaining both sustainability and affordability for residents.
What the inspection will cover
Beginning this month, crews will examine 4,451 manholes in stages through 2028. Work includes vapour testing across 281,760 metres of sewer mains to pinpoint problem areas. Officials note that manholes are particularly vulnerable to leakage in groundwater-heavy areas.
Long-term goals for North Surrey
The city describes the program as part of a “targeted investigation and rehabilitation strategy” aimed at preventing sewer overflows and protecting water quality. By identifying vulnerabilities early, officials hope to reduce expensive emergency repairs in the future.
How residents may be affected
While much of the work will take place underground, residents may notice temporary crews in neighbourhoods as inspections progress. The city has not announced service disruptions but says regular maintenance and testing are essential to safeguarding public health and infrastructure.
